I don't fully agree with that. - Cheaper: Well most decent banks I have been working with don't charge on USD wires, or they charge something like $20 flat, which happens to be on par or cheaper than the ethereum blockchain fees nowadays - Faster: In my experience (in sending hundreds of wires every month), the actual "sending time" of USD wires via Fed wire or SWIFT is literally minutes, so that's on par with blockchains. Most of the time the funds are just stuck somewhere in the compliance department. The same would hold if you withdraw/deposit USDT/USDC to an exchange. Funds can still get stuck waiting for compliance approval. - Easier: That's debatable. I guess some banking UIs are better than others. And blockchain is not particularly known to be UI/UX friendly either. One definite advantage I could think of is that when you hold USDT/USDC in your wallet, then you have full control over them, but I bet 99% of the USDT/USDC is held on exchange, and exchanges are more and more starting to act like banks (with all the slowness that that entails).
